Keto Blueberry Mug Cake Recipe

This Keto Blueberry Mug Cake Is The Ultimate Keto Microwave Muffin In A Mug (Gluten-Free, Paleo, Low Carb)

  • Author: Heather Burnett
  • Total Time: 10 Minutes
  • Yield: 1 1x
  • Diet: Gluten Free


Whether you call it a keto mug muffin or a mug cake, you need this Keto Blueberry Mug Cake recipe. It’s everything you want in an easy keto, vegan, and gluten-free breakfast or snack that’s ready in less than 10 minutes with 5.7 net carbs. 




As I mentioned, this one is super easy – everything is going down right there in your mug. 

So, grab a medium mug and mix the almond flour, coconut flour, powdered sweetener, baking powder, and salt. Make sure you do your best to incorporate this well because the integrity of the entire recipe depends on it.:) 

Now, add in the avocado oil, egg, vanilla, and the blueberries and mix it up.

Now put it in the microwave and set the timer for 1 minute ten seconds.

Because I do not know where you are microwave-wise, I feel like I need to tell you that if the mug cake doesn’t look done after a minute ten – go ahead and put it back in for 10-second intervals until it looks like a blueberry muffin. 

Top with blueberries, butter and a pinch of powdered erythritol
